L-Citrulline malate is an amino acid that enhances physical endurance due to its role in the synthesis of nitric oxide (NO) . [1]

When nitric oxide production increases, blood flow improves, allowing nutrients and oxygen to replenish muscle tissue more efficiently. This translates to greater muscle pumps and heightened energy levels.

Numerous studies have demonstrated the performance-enhancing effects of L-citrulline malate such enhancing strength, muscle power output, anaerobic and aerobic capacity [2, 3, 4]

Additionally, studies indicate that L-Citrulline Malate reduces muscle soreness and enhances immune responses during the post-exercise period, supporting recovery from physical training [5].

Beta-alanine is an amino acid that functions as a precursor to carnosine, a molecule that accumulates in skeletal muscle tissue, where it plays a crucial role in buffering the acid produced during intense physical exercise. 

Supplementing with Beta-alanine has been shown to increase muscle carnosine levels, which are quickly depleted during intense exercise [6, 7].

Research shows that supplementing with Beta-alanine can significantly improve overall exercise capacity including maximal strength and power output, particularly in exercises requiring sustained maximal effort[8].  strength [9] 

Beta-alanine supplementation may also increase lean muscle mass [10] and delay the onset of neuromuscular fatigue [11, 12]

Betaine, also known as trimethylglycine, plays a role in various physiological processes, primarily as an osmolyte (helping cells maintain fluid balance) and a methyl donor (assisting in biochemical reactions). Betaine supplementation has shown promise in improving muscle endurance and enhancing strength and power in trained individuals [13, 14, 15].

While the mechanisms are not fully understood, Betaine supplementation may promote athletic performance through regulating cellular hydration, supporting creatine biosynthesis and playing a role in ATP (energy) production. [16]

Taurine is one of the most well studied performance aids offering diverse benefits for athletes and active individuals. Evidence indicates that adequate taurine levels are pivotal for central nervous system (CNS) function and may help prevent fatigue during arduous exercise. [17]

Taurine has been shown to be effective in enhancing both aerobic and anaerobic performance while also supporting recovery from exercise. [ 18, 19] 

Several studies have demonstrated that taurine supplementation can help delay time to exhaustion and decrease rate of perceived exertion making it an important ingredient for intense physical activity. [20, 21]

Increasing tyrosine uptake may positively influence neurotransmitter-related psychological functioning. Research shows that supplementing with L-tyrosine can significantly enhance cognitive performance, especially under acutely stressful situations (such as intense training) [22].

L-Tyrosine has also been shown to improve “cognitive flexibility,” meaning it can help you adapt to changing cognitive demands without letting extraneous thoughts take over [23].

Alpha-GPC (L-alpha-glycerylphosphorylcholine) is a cholinergic compound that supports neuromuscular function and physical performance by increasing acetylcholine levels. Studies have shown that supplementation with Alpha-GPC can enhance power output and strength. [24]

Alpha-GPC is primarily found in the brain and is one of the two major storage forms of choline in the cytosol (interior space of cells), along with phosphocholine [25].

Research also suggests that Alpha-GPC may stimulate growth hormone secretion, which plays a role in muscle recovery, fat metabolism, and lean mass development. [26]

While most pre-workouts contain synthetic caffeine anhydrous, we utilize organic caffeine derived from green coffee beans (as PurCaf®). 

Caffeine is a well-documented ergogenic aid that enhances physical and cognitive performance. Research indicates that caffeine improves performance by reducing perceived exertion and delaying fatigue through adenosine receptor antagonism, increasing central nervous system excitability. [27, 28]

Caffeine enhances muscle strength and power output by facilitating calcium mobilization and neuromuscular transmission [29].

L-Theanine is an amino acid found in green tea known for its ability to promote nervous system relaxation without sedation. In the context of athletic performance, it is often combined with caffeine in pre-workout supplements to enhance focus, reduce jitteriness, and improve cognitive function. Research suggests that L-Theanine modulates nervous system function, leading to improved attention, reaction time, and stress reduction—key factors for optimal workout performance. [30, 31]

Additionally, L-theanine has been shown to work in synergy with caffeine to support cognitive function and overall performance [32]. L-theanine may help smooth out the overstimulation sometimes caused by stimulants, preventing energy crashes and promoting sustained mental clarity

Theobromine is the primary alkaloid found in cocoa beans and is chemically related to caffeine, acting as a central nervous system stimulant [33].

Research has found that theobromine has differential contributions to mood and cognitive function compared to caffeine, providing further insight into the distinct yet synergistic nature of these naturally occurring stimulants [34].

The adaptogens that comprise SenActiv® are Panax notoginseng root and rose hips (Rosa roxburghii). The notoginseng in SenActiv® is highly concentrated in notoginsenoside R1, a beneficial compound that helps accelerate muscle recovery during/after intense exercise. 

Likewise, the rose hips provide several ginsenoside-like molecules that provide  synergistic recovery-enhancing effects with ginsenoside R1 [35]. 

These phytonutrients are suggested to work by bolstering a cellular "cleaning" process known as autophagy, particularly in skeletal muscle cells [36, 37, 38].

BioPerine® is a patented black pepper (Piper nigrum) fruit extract standardized for its piperine content. Piperine is a natural alkaloid known for its “bioenhancer” properties, improving the bioavailability of molecules that are typically poorly absorbed or extensively metabolized in the liver [39, 40].

Boron is an important trace mineral with numerous roles in the human body. Recent evidence suggests that men who supplement with boron daily have higher levels of testosterone and lower levels of estradiol (estrogen) than those who don’t [41].

Chelated zinc is a bioavailable source of zinc, an essential cofactor for various enzymes. Research suggests zinc is crucial for supporting fertility and sperm cell counts in men [42]. This is largely because zinc aids in natural testosterone production, and males who are zinc deficient are at a higher risk of infertility [43].

Vitamins, as a collective group, are essential micronutrients that act as coenzymes (read: "helper molecules") for processes throughout the body. Vitamins B6 and B12 are water-soluble vitamins that are particularly important for cognitive function, cardiovascular health, nutrient metabolism, and immunity [44, 45]. As such, you can't go wrong with having these in your pre-workout arsenal.

Many minerals act as electrolytes in aqueous solutions, meaning they carry an electric charge that influences concentration gradients across cellular membranes and enzyme functions. Sodium and potassium are arguably the most important electrolyte minerals, being well-known to impact hydration status and exercise performance  [46].
